Ecological roles of five-needle pine in Colorado: Potential consequences of their loss

Publications Posted on: September 30, 2016
Limber pine (Pinus flexilis James) and Rocky Mountain bristlecone pine (Pinus aristata Engelm.) are two white pines that grow in Colorado. Limber pine has a broad distribution throughout western North America while bristlecone pine’s distribution is almost entirely within the state of Colorado. White pine blister rust (Cronartium ribicola J. C. Fisch.) was discovered in Colorado in 1998 and threatens populations of both species.

Mountain big sagebrush (Artemisia tridentata spp vaseyana) seed production

Publications Posted on: September 15, 2016
Big sagebrush (Artemisia tridentata Nutt.) is the most widespread and common shrub in the sagebrush biome of western North America. Of the three most common subspecies of big sagebrush (Artemisia tridentata), mountain big sagebrush (ssp. vaseyana; MBS) is the most resilient to disturbance, but still requires favorable climactic conditions and a viable post-fire seedbank for successful unassisted recovery.

Northern goshawks on the Kaibab Plateau: A 20-year investigation into factors affecting their demography

Science Spotlights Posted on: August 26, 2016
The elusive northern goshawk, its forest habitats, and the habitats of its bird and mammal prey are significant conservation issues related to the management of forests throughout the hawk’s North American range.  The Rocky Mountain Research Station has been enumerating the population size and documenting the population ecology and demography of individual goshawks on Arizona’s Kaibab Plateau for 20 years with the objective of identifying the vegetation composition and structure of forests habitats that best supports their survival and reproduction.

Quantifying the combined effects of climate, fire, and treatments on the connectivity and fragmentation of wildlife populations across the Great Basin

Projects Posted on: August 17, 2016
Over one million acres will receive treatments across the Great Basin Landscape Conservation Cooperative (GBLCC) to conserve greater sage-grouse habitat over the next decade. These treatments are intended to restore native sagebrush habitat by reducing encroachment of juniper, infestations of invasive weeds, and wildfire. This project will evaluate the effects of vegetation treatments on population connectivity, genetic diversity and gene flow of wildlife species across the full extent of the Great Basin Landscape Conservation Cooperative.

Northern Eurasia black carbon

Science Spotlights Posted on: August 16, 2016
Scientists examined daily black carbon emissions from fires over different land cover types in Northern Eurasia. Their results are critical in understanding the future impacts of climate change on the fire dynamics in Northern Eurasia and the contribution of black carbon to accelerated melting of Arctic ice.

Models for quantifying smoke emissions and impacts

Projects Posted on: July 25, 2016
In this study, we determined the locations of wildfire-derived emissions and their aggregate impacts on Salt Lake City, Utah, a major urban center downwind of the fires. The USFS Rocky Mountain Research Station’s new Wildland Fire Emission Inventory Version 2 model was used to determine the location and timing of wildfire emissions.

Climate adaption and post-fire restoration of a foundational perennial in cold desert: Insights from intraspecific variation in response to weather

Publications Posted on: July 15, 2016
The loss of foundational but fire-intolerant perennials such as sagebrush due to increases in fire size and frequency in semi-arid regions has motivated efforts to restore them, often with mixed or even no success. Seeds of sagebrush Artemisia tridentata and related species must be moved considerable distances from seed source to planting sites, but such transfers have not been guided by an understanding of local climate adaptation.

The Front Range Forest Reconstruction Network

Documents and Media Posted on: June 14, 2016
The Front Range Forest Reconstruction Network (FRFRNet) was designed as a regional sampling effort to both: 1) provide locally-relevant reference conditions to guide restoration and 2) to increase our understanding of the regional ecology, chiefly the interaction between forest structure and fire across large spatial environmental gradientsand long timespans.

RxCADRE 2012: Instrument and infrared target survey locations and attributes

Datasets Posted on: June 08, 2016
This data package contains one shapefile of 875 target survey locations of the 2012 burns from the Prescribed Fire Combustion and Atmospheric Dynamics Research Experiment (RxCADRE) project. This peoject was a collaboration of 30 leading fire scientists across 6 fire disciplines to collect various data on 7 large operational prescribed fires in 2008 and 2011 at the Eglin Air Force Base in Okaloosa County, Florida and the Joseph W.

Data supporting publication of fortifying the forest: thinning and burning increase resistance to a bark beetle outbreak and promote forest resilience

Datasets Posted on: June 08, 2016
This package contains data used for the publication "Fortifying the forest: thinning and burning increase resistance to a bark beetle outbreak and promote forest resilience" (Hood et al. 2016). This study includes measurements from 1996-2012 at the Lubrecht Fire-Fire Surrogate Study Site, which was established in 2000 and includes four treatments, an untreated control, prescribed burn, a thinning, and a thinning followed by prescribed burn.
